VALVE.

SPECIFICATION forming part of Letters Patent No. 770,088, datedSeptember 13, 1904.

Application filed July 1, 1904. Serial No. 214,922. (No model.) v

To all whom, it may concern:

Be it known that I, ILA N. MOORE, a citizen of the United States,residing at the city of Battlecreek, county of Calhoun, State ofMichigan, have invented certain new and useful Improvements in Valves,of which the following is a specification.

This invention relates to improvements in Valves.

My improved valve is particularly adapted for use as an intake-valve forair or gas compressor cylinders, and I have illustrated and described itin that relation herein, although it is desirable for use in otherrelations.

Much difliculty has heretofore been experienced in producingsatisfactory intake-valves for use on air and gas compressors and thelike, as owing to the great amount of work done thereby the valves ingeneral use in that relation very soon get out of repair, veryfrequently causing serious injury to the apparatus.

The objects of this invention are: first, to provide an improved valvethat is adapted for use as an intake-valve for air or gas compressors orthe like, which is assembled without the use of bolts, nuts, or screws;second, to provide an improved valve adapted to perform very heavy workwithout liability of getting out of repair, the parts of which aresimple and economical in structure and easily assembled.

Further objects and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawings, forming a part of thisspecification, in which Figure 1 is a cross-sectional view through thecylinder-head of an air or gas compressor with my improved valve inposition therein.

the head of an air or gas compressor cylin'- der. The valve-casing ismade up of openended cylindrical sections B and B. The section B is theinner section of the casing and is provided with external screw-threadsat its inner ends, whereby it is secured in position in a suitablethreaded opening in the cylinder-head. The casing-section B is enlargedat its outer end to receive the outer casingsection B, which isscrew-threaded therein. The inner section is provided with a suitablevalve-seat at its inner end and with an annular shoulder or seatb forthe ring E, the purpose of which will be hereinafter pointed out. Thevalve C is provided with a stem 0, which is formed integral therewith.The valve-stem c is provided with radial web-like projections 0. Theseprojections c fit loosely within the casing at their inner ends to guidethe valve into its seat, but are cutaway, as at 0, toward their outerends. A ring O, adapted to loosely fit within the valve-casing, so as toreciprocate freely therein, is formed on the web extensions of thevalve-stem at their outer ends. A coiled springD is arranged upon thevalve-stem, as clearly appears in Fig. 3, one end bearing against thering O and the other against the ring E. This ring E projects into thecasing sufficiently to serve as a stop for the ring O, therebypreventing the removal of the valve from the casing when the ring E isin position. The ring is held in position by the outer casing-section B,which screws down upon it. This ring E is made up of segments, so thatit may be put in position after the valve-stem is inserted through thevalve-casing section B. The spring D is then placed upon the stem, andthe outer casing-section B screwed into position. The valve is thus freeto reciprocate, and it is impossible for it to be entirely withdrawnfrom the casing on account of the ring E engaging the ring of the valve-Stem. I am thus enabled to do away with any screws or nuts as a part ofthe valve. This is of very great advantange in such structures as air orgas compressors, as the valves therein are required to perform veryheavy work, the vibration of the valve quickly loosening the parts ifthey are put together with bolts, nuts; or screws. In myimproved valvethe movable parts are secured without resorting to such means. The partsof my improved valve are also economical in structure and are easilyassembled. I have illustrated and described the same in the formpreferred by me on account of its structural simplicity and economy,although I am aware that it is capable of considerable structuralvariation without departing from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with an air or gas compressor cylinder, of avalve-casing made up of an inner section having a valve-seat at itsinner end and an internal seat or shoulder; an outer sectionscrew-threaded into said inner section; a ring made up of segmentsclamped between said shoulder in said inner section and the inner end ofsaid outer section; a valve having a stem with radial web-likeprojections thereon, said projections fitting loosely within saidvalve-casing at its inner end; a ring fitting loosely within saidvalve-casing, the same being a part of the valve-stem at its outer end;and a coiled spring arranged on said stem bearing against said ring insaid casing and the ring on said stem, for the purpose specified.

2. The combination with an air or gas compressor cylinder, of avalve-casing made up of an inner section having a valve-seat at itsinner end and an internal seat or shoulder; an outer sectionscrew-threaded into said inner section; aring made up of segmentsclamped between said shoulder in said inner section and the inner end ofsaid outer section; a valve having a stem with radial web-likeprojections thereon; a ring fitting loosely within said valve-casing andbeing a part of the valvestem at its outer end; and a coiled springarranged on said stem, bearing against said ring in said casing and thering on said stem, for the purpose specified.

3. The combination with an air or gas compressor cylinder, of avalve-casing made up of an inner section having a valve-seat at itsinner end and an internal seat or shoulder; an outer sectionscrew-threaded into said inner section; a ring made up of segmentsclamped between said seat or shoulder in said inner section and theinner end of said outer section; a valve; a stem therefor; a head onsaid stem fitting loosely within said valve-casing; and a coiled springarranged on said stem bearing against said ring in said casing and saidhead on said valve-stem, for the purpose specified.

4. The combination with an air or gas compressor cylinder, of avalve-casing made up of an inner section having a valve-seat at itsinner end and an internal seat or shoulder; an outer sectionscrew-threaded into said inner section; a ring made up of segmentsclamped between said seat or shoulder in said inner section and theinner end of said outer section; a valve; a stem therefor; a head onsaid stem fitting loosely within said valve-casing; and a return-springfor said valve, for the purpose specified.

5. The combination with an air or gas compressor cylinder, of avalve-casing made up of an inner section having a valve-seat at itsinner end and an internal seat or shoulder; an outer sectionscrew-threaded into said inner section; a ring made up of segmentsclamped between said seat or shoulder in said inner section and theinner end of said outer section; a valve; a stem therefor; and a coiledspring arranged on said stem bearing against said ring in said casing,for the purpose specified.

6. In a valve, the combination of a casing made up of an inner sectionhaving a valveseat therein; a ring made up of segments; an outer sectionscrew-threaded into said inner section adapted to retain said ring inposition; a valve; a stem therefor; a head on said valvestem fittingloosely within said valve-casing; and a return-spring for said valve,for the purpose specified.

In a valve, the combination of a casing made up of an inner sectionhaving a suitable valve-seat therein; a valve; a stem therefor; a headon said stem; stops arranged within said inner valve-casing section; aspring on said valve-stem adapted to rest against said stops; and anouter valve casing section screw-threaded into said inner valve-casingsection, adapted to retain said stops in position, for the purposespecified.

9. In a valve, the combination of a casing made up of an inner sectionhaving a suitable valve-seat therein; a valve; a stern therefor; a headon said stem; stops arranged Within said inner valve-casing section; andan outer valve-casing section screw-threaded into said innervalve-casing section, adapted to retain said stops in position, for thepurpose specified.
